What aload of rubbish - prove it, we have over 320 users in the UK alone using the SACP0307 solder with great results, and the biggest advantage they have is they can multiple source the solder not stuck to one company who has purchased the patent and charge extortionate amounts due to that. Wetting of 0.3% Ag is only 0.1C below 3.0% Ag yet considerably faster than the other tin copper derivatives. Cheers Greg
